Hello!
In 1973 the Nazis began an attack against art by looting and losing many works of art. Among the artists whose art was branded as "degenerate", expropriated and hidden are: Picasso, Matisse, Botticelli, Chagall, Monet, among others.
The Nazi regime banned the so-called "degenerate art" by organizing an exhibition in Munich that would stigmatize it, while simultaneously glorifying "pure Aryan art". It was when the looting of art began in the museums of the occupied territories and in the houses of collectors and Jews. On the walls where they were displayed, comments were read as "incompetent charlatans", "insult to the German heroes of the great war" and
"decadence exploited for literary and commercial purposes".
I hope this can help you.
Regards!
